Doctor Strange is Marvel's Sorcerer Supreme, a master of portals and time who appears across comics, films and hero-based games where his ultimate ability is a major play. This very short bye clip circulates on soundboards as a reaction to his teleport-style exits, trimmed so tightly that only the start of the word survives. Its popularity online comes from that brevity, as gamers and editors reuse the cut-off greeting for any sudden disappearance, rage quit or portal escape, rather than for a full dramatic ultimate moment.
